Most common issues in MMOs that need GM intervention

Well the topic title says it all, I was just wondering what you folks feel to be the most common issues we players encounter in MMOs as general, not only WoW (ingame that is) that require GM assisatance - be it stuck, mobs, loot, skills or really any kind of bugs that cross your mind and gaming experience.

Most people I know just give up if there's a bug, but if they don't get their pet in the mail, then they rage.

From my own experience it's when something doesn't show up in the mailbox i.e gold from the auction house or stuff sent from one toon to the other. I also think they receive many tickets regarding harassment issues.
